For Android devices, is internal storage memory typically faster, slower, or equal to microSD card storage? For example, let's take the Samsung Galaxy S10 Android phone. It comes in 128GB, 512GB, and 1TB storage configurations. It also has a single microSD card slot. The cost difference between the different tiers of integrated storage is slightly more than cost of a comparable microSD card, but not a big difference. Which will result in better performance: An Android device with only integrated storage, or one with an equivalent amount of storage in the form of integrated storage + a quality microSD card?
